Re: [Losmandy_users] PEC while autoguiding on G11?

I remember discussion from years ago on this topic, should I bother

using the PEC feature on the G11 when I'm autoguiding. I ended up

deciding I didn't need to bother. I use an STV autoguider. However,

someone at the dark sky site brought this up last time I was out, and

said that he did do this with his G11/autoguider, and that it did

improve results.



Anyone actually test this? What were the findings?



Apologies if this is a FAQ ;-)



Thanks,

Hi Dick,



It is a FAQ ... but there isn't any simple answer to the question. My

personal experience is that PEC does not improve a guided image. In fact

it sometimes makes it worse. But there is a caveat with this and that is

that *if* you have Gemini with the new Level 4 ROM, Pempro and a laptop

then you can improve things considerably. But if you want to keep things

simple, ie: no laptop, then I wouldn't use PEC. Your mileage may

certainly vary.



Regards



Bill
